What does the warning tell you? That you're trying to return something in a method that returns void (IBAction is the same as void). It sounds like you could use another run through the introduction topics on Objective-C and Cocoa in general.


  What exactly are you trying to accomplish in this method?

Hi, I am trying to accomplish a simple task with an IBAction but apparently it is not clear how can I return from an IBAction. My action looks like this:

- (IBAction)myAction:(id)sender
{
    //Some check
    if (some_thing != other_thing)
    {
        NSAlert * myAlert;
        //Create the alert
        [myAlert beginSheetForModalWindow:...];
        return ???
    }
    //Other code
}

Well, the 'Other code' should only be called if the check catches an error so normally I would return nil or something else but then I receive a warning that "return with a value, in function returning void". How can this be done?

Thanks for any help,
